A recent upgrade of Notepad++ had an annoying auto-complete popup appearing and I could not find a way to shut it off permanently. It's now in the Recycle Bin.

So I've changed over from Notepad++ to Sublime Text when modding.
Thanks JBW for bringing it to my attention some time ago.

Couple of advantages in the first 5 minutes.

The 'Find' functions are better IMO. Easier to use and easier to understand.
Also scrolling down the page is easier with the image based scroll section (you'll see what I mean) Very handy when jumping back and forth to code further down the page. Plus it doesn't jump back to the top of the screen if you go past the bottom of the page. A feature of most programs I've never understood.

Most importantly, within about 3 minutes I was able to change the 'Find in Files' hotkey from 'Ctrl-Shift-F' to'Ctrl-F' just to make it easier. Normally I struggle to find and use any of the nice customizing features but it was straight-forward and very intuitive in this program.
